Constant disk activity
Posted: 29 Oct 2025, 17:52
I received my F2-425 Plus last week. I upgraded the RAM to 32GB, installed two 256GB WD SN700 as system disks and two 18TB WD Red Pro in RAID 1 as Storage Pool 1. I then formatted the pool in EXT4 to create Volume 1 and copied about 10TB of data to it. There is no Hypercache. TOS is 6.0.783-01200. The only app installed is Web Server but it is not enabled.
The problem is that the HDDs keep chugging away at about 3% Write instead of going into hibernation after 30 minutes. Following the advice in an earlier similar thread, I used the pdstat command and captured the following:
Please could someone tell me what's going on and how to stop it.
